Question 1

Find the coefficients of the expansion of $(3a-b)^3$ . That is, represent $(3a-b)^3$ as

$\alpha_0a^3+\alpha_1a^2b^1+\alpha_2a^1b^2+\alpha_3b^3$

Try to compute these coefficients using the binomial theorem (instead of multiplying $(3a-b)$ by itself two times).

Enter the values $\alpha_0, \alpha_1, \alpha_2, \alpha_3$ . Separate the values by commas, avoid spaces, do not include plus signs.

For example, for the question $(3a-b)^2$ the answer would be: 9,-6,1

1 / 1 point

27,-27,9,-1

Correct

Exactly!
